TELESGOPING STRAW-STACKER.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed December 20, 1907. Serial No. 407,421.

To all whom it may concern:

Be it known that 1, JOHN R. BUOKWALTER, a citizen of the United States,residing at Kinzers, in the county of Lancaster and State ofPennsylvania, have invented certain new and useful Improvements inTelescoping Straw-Stackers, of which the following is a specification,reference being had therein to the accompanying drawing.

My invention relates to a telescoping straw-stacker adapted to be usedin connection with a thresher-machine; one object of the invention beingto provide a novel construction of stacker capable of elevating thestraw perpendicularly without becoming clogged, carrying the chaff anddirt as well as the straw.

Another object is to provide a telescoping stacker in which the uppersection may be made much longer than the lower section, and capable oftelescoping down upon said lower section until their upper ends areapproximately flush, thus providing a longer stacker when in use andwhich is capable of compactness for shifting in the barn and fortransportation.

Another object is to provide a novel forcefeeding device to deliver thestraw from the tihresher to, and underneath the elevator rag.

I have here illustrated my invention as applied to the usual design ofthresher, but it may be applied to any well known make of thresher orstacker, and I do not confine myself to the exact construction as shown,as slight changes may be made in the construction without departing fromthe spirit of the invention.

In the drawings forming part of this specification: Figure 1, is a viewshowing the rear end of a thresher in elevation, with my telescopingconveyer raised, and showing the auxiliary feeder. Fig. 2, is anenlarged view of the lower end of the conveyer, showing the feeder andactuating mechanism more in detail. Fig. 3, is a plan view of theconveyer, hopper and auxiliary feeder. Fig. 4, is a sectional view onthe line y y, of Fig. 2. Fig. 5, is a sectional view of the turn tableon the line a x of Fig. 2. Fig. 6, is a view of the feeder shaft,cross-heads and rakes removed from the conveyer.

Like figures indicate corresponding parts in all the views of thedrawings.

In the drawings :1, indicates the bedtimbers of a threshing machineextended to form supports for the turn-table 2, which is mounted thereonin the usual way, by circular tracks and pivot pin, and to the uppersurface of which is rigidly secured the hopper 3, which is made with adownwardly inclined bottom adapted to receive the straw from thethresher, down the inclined surface of which it slides to the auxiliaryfeeder, which will hereinafter be more fully described. To the forwardends of the bed-timbers 1, are secured in a hingeable manner the lowerends 5, and 5, of the lower section of the conveyer trough by the lugs6, and 6, and the shaft 7, passed therethrough. The conveyer or stackeris constructed of the sections 8, and 9, the upper section 9, beinglonger than the lower section 8, and telescoping downward upon the lowersection 8, which is hinged to the bed-timber of the thresher asheretofore described. Said sections being in the form of hollow troughs,the upper section sliding upon the lower section and provided with aslightly enlarged and outwardly curved mouth at the top, and the lowersection having enlarged lower ends to its sides which are hingeablymounted upon the bed-timber of the thresher and a downwardly andupwardly curved bottom between the inner sides of which is mounted thefeeding device.

Near the upper end of the lower trough section are mounted the trussesor brackets 10, which are rigidly secured to the upper edges of thesides of said trough by the bolts 11, and are provided with the off-setarms 12, and 13, to the ends of which are pivoted the guide rollers 14,and 15; the guide roller 15, bearing against the lower edge of the uppertrough side, while the arm 12, carrying the guide roller 14, is madeslightly longer to allow the lower end of the upper section to dropslightly as it descends to enable it to freely pass the enlarged part ofthe lower section. The trusses are further secured and braced by the rod16, extending across the top of the trough and rigidly secured to bothtrusses, and upon which are mounted idle rollers 54, to support andguide the conveyer belt or drag. To one end of the truss arms 12, issecured the supporting cable 17, which extends over the pulley 18, onthe thresher frame and thence secured to the Windlass 19,which isoperated by the chain 20, the sprocket 21, and the hand-crank 22, thewhole adapted for raising and lowering the conveyer as desired.

Secured to the outer surfaces of the sides of the upper section of thetrough near its lower end, are the lower ends of the adjusting cables23, which are passed over the grooved wheels 24, which are rotatablymounted upon the trusses 10, and thence down and over the grooved wheels25, mounted upon the shaft 26, and keyed thereto, said shaft beingjournaled in the sides of the lower section 8, and then upward to theouter sides of the upper section 9, where their ends are secured in apositive manner to keep said cables in a stretched position.

Upon the shaft 26, is mounted upon one end thereof, inside of the wheel25, a ratchet wheel 27, keyed to said shaft, while the end of said shaftis squared and fitted with a hand -crank 28, by which the shaft andwheels may be rotated, which will carry the cables 23, by friction andthus extend or telescope the upper section of the conveyer upon thelower section thereof, where it may be held in any desired position bythe pawl 29, engaging the ratchet 27. Mounted within the lower sectionof the conveyer trough 8, near its lower end is the shaft 30, whichcarries the drum 53, keyed thereon, one end of said shaft 30, beingextended through and beyond the side of said section, and having keyedthereon the sprocket wheel 31. Mounted near the upper end of the uppersection 9, is the roller 32, while around said roller 32, and the drum53, is passed the elevator endless belt or drag 33., upon the outersurface of which are secured the transverse cleats 34, which are soarranged that they come in contact with the surface of the bottom of thetroughs. Mounted between the lower ends of the lower section 8, of theconveyer, and journaled in the sides thereof is the shaft 35, to whichare rigidly secured the cross-heads 36, of the feeding device; the endsof said cross-heads being provided with bearings 37, and ca s 38, and inwhich bearings are mounted t 1e rake-arms 39, by the cranked shapedextension of the end teeth 40, which are bolted to said rake-arms, andto which are also secured the teeth 41.

To the inner sides of the lower section concentric with the auxiliaryfeeder shaft 35, are mounted the cam-races 42, in which travel thecranked extensions of the rake-arms 39, in such a manner that therake-teeth are extended in a radial direction from the center, untilthey reach the flattened part of the cam-race, where they are drawn inso as to turn the rake-teeth into a right angle position with relationto the axis of said shaft, see dotted lines in Fig. 2, thus allowingthem to freely pass by the conveyer-belt and also be cleaned of straw atthe same time, by the action of said conveyer-belt passing in anOpposite direction from the revolution of said feeder.

To the projecting end of the shaft 35, be-

eosnse yond the conveyer side is keyed the double sprocket wheel 43,which is of larger diameter than the sprocket wheel 31, to which oneside of it is belted by the chain 44, and the other side to a sprocketwheel 45, which is keyed to the pivot-shaft 7, and is driven by zontalshaft 51, which is journaled to the turn-table frame 2, and extendsslightly beyond the same, and has secured thereon the pulley 52, whichis belted to the thresher.

The turn-table 2, is pivoted upon the bedtiLnber 1, by the sleeve 54,which is flanged at its top and belted to the under side of said turntable and is secured at its lower end to the miter gear 55, which mesheswith the gear 56, mounted on the horizontal shaft 57, secured inbearings in the bed-timber 1, of the thresher, and operated by ahand-crank.

The operation of my device is as follows The telescoping members 8, and9, being lowered from the thresher by the hand-crank 22, and cable 17,to the desired height, the turn-table 2, is swung around by its turningmechanism so as to bring it into the desired position, either directlyout from the rear of the thresher or at an angle to the same. The pawl29, is now raised from engagement with the ratchet wheel 31, and thehand-crank 26, is rotated towards the thresher, which action will rotatethe grooved wheel 25, carrying the cable 23, which will extend the uppersection of the conveyer until the elevatorbelt or drag is extended andbrought to the desired tension, when the pawl 29, is allowed to dropinto engagement with the ratchet wheel 31, thus securing the telescopedsections in the desired position. The pulley 52, is now rotated by powercommunicated by the belt 59, giving ower to the trainof gears andchains, where y rotating the auxiliary feeder and the endlessconveyer-belt, and by the proportion of the gears the elevator-belt willtravel at about four times the speed of the feeder. The straw is nowdelivered by the thresher upon the hopper, down which it slides untilcaught by the rake-teeth of the feeder by which it is fed to the underside of the endless elevator-belt or drag and thereby dragged up thebottom of the conveyer trough by the cross-slats of said conveyerpressing said straw against the trough bottom and delivering it from thetop of said conveyer.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a straw-stacker of the classdescribed,

ing one upon the other, a brace-truss secured to the lower member andembracing and guiding said upper member, a cable secured to said truss,a guide pulley and Windlass secured to the thresher, and operating saidcable, an endless elevator drag mounted within said conveyer, and meansfor rotating said drag, an auxlliary feeding device rotatably mounted inthe lower end of said conveyer, and means for rotating the same, for thepurpose set forth.
